Guys, I know this has been beaten to death but I cannot find a satisfactory answer from someone who has actually verified it. I have a Gen 3 G32 (.357) barrel that I want to use in my soon to arrive Gen 4 G23. Will this work? I have heard: 1. Yes it will 2. No it wont 3. Glock says it wont but it will 4. The barrel has differences in the guide rod area but it will work 5. The barrel has differences in the guide rod area and it will not work What is the real answer by someone who has been there and done that?
